Transmission unit provided with a swash plate (variants) and differential speed converter (variants) based thereon

摘要

A transmission and speed conversion device is provided with a wobble (presessional) plate. The transmission unit has two cases encompasing each other. The first case is embodied as a wobble plate in that it is capable of two independent motions: rotation and pressession around its own axis which is inclined with respect to the axis of the second case. The adjacent side surfaces of the two cases are embodied in the form of a shperical belt, the center of the sphere being disposed at the center of precession of the wobble plate. Race grooves are embodied on the adjacent case surfaces and communicate with each other via rotation bodies. The race grooves are inclined to each other where they contact the rotation bodies at an angle less than the self blocking angle of the wobble plate, allowing the device to operate in such a way that the rotation bodies are slip-free. The device can be provided with a system of angular races parallel with each other, and can operate as a friction-planetary transmission in which pressure is automatically regulated by load.
